Yet, the third season of the show (Thursdays, 8.30pm, SoHo) might be its broadest and most accessible season yet, judging from the first two episodes. We catch up with the girls, and guys of Girls, in the wake of events that ended season two.
Hannah (Dunham) and Adam (Adam Driver) are in some semblance of domestic bliss, enjoying a kind of symbiotic relationship based on mutual reliance and a "keep moving forward" mentality. Even an emotionally jarring - but riotously funny - run-in with Adam's season two girlfriend Natalia and a friend (played by Shiri Appleby and Amy Schumer), which opened the new season, can't kill the buzz the two have got going on.
By the time Adam calls Hannah his "best friend" in the middle of the second episode, you start to suspect the pair might be in this for the long haul.
Marnie (Allison Williams) and Shoshanna (Zosia Mamet) don't get a lot to do in the early going, with both characters recovering from their recent breakups from Charlie and Ray, respectively.
The best material of the opening episodes actually involves Jessa (Jemima Kirke), who starts the season in rehab - explaining her absence during the latter stages of season two - and under a man ban, thanks to "fraternising" with the opposite sex and causing a multitude of problems during group therapy sessions.
Kirke does a great job in the scenes, perfectly encapsulating Jessa's philosophical outlook despite the characters' obvious world-weariness, and gets to play with some high-profile guest stars in Richard E Grant and Danielle Brooks; Brit star Grant gets up to mischief and challenges Jessa's thinking, while Brooks - best known as Taystee on Orange Is The New Black - unwittingly becomes a target in those group sessions.
While the early episodes of season three do deal with some heavy subject matter, they also manage to be the lightest and funniest episodes of the show in some time without undermining the serious nature of the story, a perfect balance between the laughs that we know the show is capable of and the more dramatic fare Dunham likes to tackle.
The second episode, in which Hannah, Adam and Shoshanna take a road trip to collect Jessa from rehab, might be the most entertaining half hour of Girls to date, whether it's Shoshanna buying a rocking chair as a souvenir, or Hannah trying to explain Truth Or Dare to a bewildered Adam, or Shosh exclaiming, "If they have turkey bacon here, I will be very surprised".
And it still manages to end on an emotional note; the final scene, in which a reunited Hannah and Jessa share the back seat back to New York, is all kinds of heart-warming.
Dunham also turns in some of her best work as a director. These are two extremely tight, consistent episodes, firing on all cylinders, and a welcome return for a show that has been patchy over its first two years. Hopefully this is a sign that Girls has taken a leap forward, creatively speaking.
I'm looking forward to seeing the rest of the season unfold.
